To all whom. it may concern.:

Be it knownthat we, Jeux F. CRAIG and IILLIAM D. Cano, citizens of the United States, residing at Oakland, in the county of Coles and State of Illinois, have invented certain new and useful Improvements in Broeders: and we do declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it. appertains to make and use the same.

This invention relates to improvements in brooders.

The object ot' :he invention is to provide an improved construction of brooder in which the brooding compartment is arranged above and entirely separate from the heating chamber.

A further object is to provide means whereby the diiferent parte ot" thelnooding compartment will be heated to different tem- ,peraturen thus permitting the chicks to select a place having a temperature they desire.

'With these and other objects in view, the invention consists ot certain novel features of construction, combination and arrangevment of parts as will be described and particularly pointe out in the appended maims.

In the accompanying drawings, Figure l is a side elevation of a broeder constructed in accordance with the invention; F ig. 2 is a horizontal section through the heating' compartment of the broeder showing a portion of the floor of the brooding compartment. Fig. 3 is a longitudinal vertical sectional view of the brooder taken on a line through the discharge openings of the heat conducting tube; Fig. i is a transverse vertical seetional view through the brooder taken on a line through the heat conducting tube; and Fig. 5 is a detail sectional view through one end of the heating compartment and the heat conducting tube, showing a modified arrangement of the latter.

Referring more particularly to the drawings, 1 denotes the brooder, which consists ot' an upper brooding compartment i, ha rin g;- in on'e side a door, 3, and a lower heating chainber or compartment, 4, which is arranged immediately below the brooding rompartment and is entirely separated therefrom by a sheet metal partition, 5, which forms` the iioor. of the brooding compartment.

In the heating compartment or chamber is arranged a series of transversely disposed partitions, (i, which separate the heating compartment into a series of heat passages, T. 1n the upper portion ot' the partition, t3, adjacent to one end oi the same is formed an opening, 8, said opening being provided for the passage of heat from one heat passage to the other, said openings forming communiation between the heat passages, T, whereby the heat-from one of said passages enters the other. The openings,8, are arranged at the opposite end of each alternate partition, (i, thus providiri for a circuitous or zigzag passage of the `Iieat through the compart ment, 4.

At one end of the heating compartment, it, between Said end and the adjacent partition, t3. is formed a heat inlet chamber, 9, in which is arranged a. transversely vdisposed heat conducting tube, 10, said tube being here shown and is preferably of I'lat, oblong shape and has one end ther-cot projecting through the bottom of the heating compartment, where it is adapted to receive the upper end otl the lamp chimney, by means ot' which the compartment is heated. The lower' side ot' the tube is preferably formed b v the bottom of the compartment, Lt, said bottom being constructed of sheet metal.

In the side walls of the tube, l0, adjaent 1o its` inner end are formed oppositely disposed heat discharging passages, il. through which the heat from the lamp enters theI chamber, 9, and from thence passe.`- through the openings, 8, and heat passages, T, to'tta opposite end of the heating cannpart nient. l. .\rranfed above the diwhargc passages, il, oi the heat tube and suitably cured to the latter by a supporting bracket is a heat detlecting plate, 1Q, which receives the heat from the passages, il, and causes the same to radiate in ditierent dirtwtions in the chamber, 9.

'lhe sheet metal partition, 5, which forml the bottom of the brooding conipartment is supported at one end of the heating compartment b v the transverse partition", t, while over the chamber, il, tlic pariitiorA if prei'crably supported b v means. of a bracket, IIB. which is secured at .its lower und to the upper Iside of the lient tube, l0. It has been 'found necessary to support. this end of the sheet, metal partition` to prevent tht` same 'from being vibrated b v the chicks: parsing thm-cover, as the vibrations of the partition lol:

'llU

' would cause the air in the chamber, 9, to

extinguish the l' ht of the heating lamp. Iii the side wa s of the heating compartment lat the end of each of the passages, 7, l

and in the heating chamber, 9, are formed heat discharging openings, 14, by means of which the temperature in the various coin- -partments may be regulated. The openings, 14, arecovered by pivoted valve plates, l5,

i which are adapted to open and close the openings,v 14, when desired.

In Fig. of the drawings is shown a slightly modified arrangement of the heat conducting tube and its connection with the ,15 heating lamp. In the form shown in Fig. 5,

the heating tube is extended through one side of the heating compartment, and said .A extended end is connected with the heating compartment, whereby the heat is brought au l into the chamber, 9, through the side of the heating compartment instead of through the bottom, asshown in the first figures or' th'e drawing. On the sheet metal partition, 5, which forms the floor of the brooding compartment is arranged a series of upwardly projecting plates, ll, which a're'so arranged as to provide a passage between each end ot' the plates and adj aeentplates or sides of the brooding chamber. The plates, 1.1, are pro- ?,Ovvicled to prevent the chicks from crowding one another, and, at the same time, the plates will not interfere with the free movement ofthe chicks in the brooding chamber. By "the provision of the plates, 11, the weaker chicks will be protected from being crowded and smothered-by thestronger chicks.

A'broocler constructed in accordance with your invention has the brooding compartment; separate entirely troni the heating 40 compartment so that the heated air or fumes from the lamp cannot possibly enter the brooding compartment, said compartment being heated entirely from the heat in the chamber below, the latter being so arranged as to provide fora graduation of the heat from one end to the other, thus enabling the chicks to select a lace having the desired temperature. The lirooder may be provided with any suitable support, and is here shown as having legs, 16, arranged at each corner and projecting',I upwardly above the heating compartment to form standards which hold the upper brooding compartment in'place upon the heating compartment. The upper 55 side of the brooding compartment may, if deaired, be provid ed with a removable cover, 17. .Y From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will'be readily understood without requiring a more extended explanation. Various changes in the form, proportion entirely separate trom said brooding coinpartinent, a sheet metal partition between said compartments, said partition forming a bottom tor the brooding compartment, a se,- ries ot' transverse partitions arranged in said beatingl compartment, said partitions having 'Formed therein air passages, said passages being` arranged at opposite endsin the adjacent partition, a heat conducting tube arranged in one end of said heating compartment, said tube having a heat inlet adapted to be connected with the heat supply, 'and a heat deleeting' plate arranged over the inner discharge end of the tube.

ln a broeder, a brooding compartment, a heating` compartment arranged beneath said brooding compartment, a series of transverse partitions arranged in said heating` compartment to divide the same into a series ot' heat passages which communicate with each otherat their opposite ends, and each ot' which is provided with a heat discharge opening, a valve plate to open and close said discharge opening, and a heatronduoting tube arranged in one end of the heating' con'ipartment.

3. ln a broeder, a brooding compartment, a plurality of pairs of short upwardly projecting plates, certain oi the pairsarranged at right ang-les tolthe others on the floor of said compartment' to provide oppositely disposed pi'issages whereby the chicks are prevented from crowdingr oneanothei.

-l-. ln a broeder, a brooding compartment, a heating ronil'iartment arranged beneath and entirely separate from said broodingl compartment., means to distribute heat through the heating compartment, and a plurality olf pairs oi plates arranged ori-thc lloorot the brooding eomliiartment to prevent the chicks from ormvding, certain 'of said pairs being arranged at. right-angles to other pairs, for the purposedescribed.

ln testimony whereof we have hereunto set our hands in presence ot two subscribing witnesses.
